Changjiang River Railcum-Road Bridge in Huanggang City:

Model:DZJ-600
Project:Huanggang Changjiang River Bridge
Users:MBEC Bridge project
Quantity:1set
Hunggang Changjiang River Bridge is designed to be a cable-stayed with Wuhan-huanggang Inter-City railway and Huanggang-Ezhou Expressway dual-purpose bridge.

Total Mainly Span is 567meter and five continuous floating system with the length 1215meter(81+243+567+243+81). It is the longest cable-stayed with railway and road dual-purpose bridge in the world.
The geological feature of this area is highly weathered and granitic layer. The diameter of the casing is 3.2M and the depth of the sheet pile driving is 16M. SZ-600 had very good performace there.

Vibratory hammer is designed as per resonance theory.When the pile forcing vibratory is consistent with the soil vibratory frequency,the soil will occur resonance phenomenon.Meanwhile ,the largest amplitude,sufficient vibratory frequency and acceleration will break the cohesion between the soil and pile.In that case the pile will disintegrate from the soil in a short time.Pile-sinking resistance especially side resistance will be reduced very quickly. Then the pile sinks under the gravity.Depend on reducing the friction between the pile and the soil to sinking the pile.So it is effective to extract the pile only using a little more force than the pile self weight.As a result ,the vibratory hammer develops rapidly and broadly used in pile-driving and pile-pulling construction.
